摘要
采用陕西省关中东部1961-2003年的气候资料,对设施农业主要生产阶段(11月-次年3月)的极端最低气温、大雾、连阴天等气候限制因子的时空分布特点分析表明:极端最低气温整体上呈上升趋势,对设施农业生产是有利的;但大雾及连阴天日数大部分为增加趋势,对设施农业生产不利。针对大荔、渭河以南诸县和渭北山区等地不同的气候变化趋势,提出了发展壮大大荔县绿色瓜果菜设施农业基地、适当调减沿渭河各县的设施农业面积、有设施农业发展潜力的北部县应重点解决好温室灌溉和冻害防御问题等建议。
Based on the meteorological data in 1961--2003 in the East of Guanzhong Areas of Shaanxi Province, the spatial and temporal distribution of the limited climate factors affected the greenhouse production in winter, such as extreme minimum air temperature, fog and continued cloudy days, was analyzed. The results showed that the extreme minimum air temperature, fog and continued cloudy days had an increased trend in winter. The trend of climate variations in the north and south of the Weihe River was different. The recommendations to promote the greenhouse production for vegetables and fruits in Dali County and properly reduce the greenhouse production in the areas along the Weihe River were put forward.
